I want to tell you,
Many believe fallen angels and satan are now dwell in hell. There is no proof find anywhere in Bible.
Wait a minute, how about Jude 6: "And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day." ?
Notice this doesn't saying they are already IN hell now. It tells us, they are already "reserved" them for their future everlasting chains under darkeness unto the judgment of the great day. That means they are already appointed for ther future eternity punishment in the lake of fire at the great white throne.
Satan and his fallen angels are now everywhere in the air over earth tempting people. When Christ comes with his angels, all fallen angels and Satan shall be cast away into the lake of fire.
There is not a single hint find anywhere in the Bible saying that Satan and fallen angels shall be cast in hell for 1000 years. Wait a minute, what about Rev. 19:20- "And the beast was taken, and with him the flase prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast into a LAKE OF FIRE burning with brimstone. "?
Does this saying that they shall be finally released out of the lake of fire after 1000 years? None.
Also, what about Rev. 20:10: "And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tornmented day and night for ever and ever."?
Premills believe only two persons - beast and false prophet shall be cast away in the lake of fire at second coming for 1000 years. But Satan(devil) is separated from them, as he shall be cast in the bottomless of pit with chained for 1000 years.
We have to be careful when we read and intepreting.
Understand Satan(devil), beast, and false prophet all are pictured as 'trinity' coped trinity of God - Rev. 16:13-14 with 1 John 5:7-8.
Rev. 20:10 doesn't mean that the beast and the false prophet is already in the lake of fire prior Satan shall be cast away into it. This is speak of three in one as trinity of satan shall be cast away into the lake of fire at once.
Also, Satan was chained and cast into the bottomless of pit for 1000 yeasr, it is not literal and physical, it speaks of figurative & symbolic of spiritual meaning. It speaks of Satan's power is now limited and restrained by God, that he cannot deceive nations, because Christ have the keys of death and hell at His resurrection (Rev. 1:18), He have power to give authority to Church, so, the church can spreading the gospel over the world (Matt. 16:18-19). 2 Thess. 2:6-8 telling us, right now, Satan is now being holding back by God, show that, he is limited and being restrain, while God allows Church to spreading the gospel to the world. When the apostasy become worsen, then time will come arrive, let Satan to be loosed out of the midst and then to revealed(2 Thess. 2:3-8).
I know Satan is still alive and he is dangerous, he is the prince of the air, he is anywhere over earth tempting people right now. He is NOT yet in the lake of fire. Beast, false prophet,devil, all three in one is still around anywhere over the earth. They are not yet in lake of fire. When Christ comes with angels, they shall be cast away in the lake of fire and stay there forever and ever, not just for only 1000 years. Also, there is no hint in Bible telling us, that they will be finally released out of the lake of fire beyond judgment day.
Therefore, there is no purgatory in the Bible.
In Christ
Rev. 22:20 -Amen!
